Is it permissible for a father to authorize one of his sons to divorce his mother, or to authorize a six-year-old girl, and would the divorce occur by the girl's saying: "Mama is divorced"? And is it valid to authorize a discerning boy?

It is permissible for a father to appoint his mature son as his agent in divorcing the son's mother, and the son is considered an agent for his father. As for a child, it is not valid to appoint them as an agent in divorce. The statement of a young girl, "Mama is divorced," does not constitute a divorce and carries no weight. One must turn away from such whispers of misgivings.
